DS1109i Glassbreak
Detector
Features
▶
Microprocessor-based SAT
▶
Automatic environmental test circuitry
▶
Built-in door or window contact
The DS1109i Detector uses microprocessor-based sound
analysis technology (SAT) to listen for the specific
frequencies associated with breaking glass. It can be used
to detect breakage of plate, tempered, laminated and wired
glass types. A built-in environmental test feature alerts the
installer of false alarm hazards in harsh environments. It is
specially designed to mount on door or window frames. A
built-in magnetic contact allows monitoring of a door or
window opening.
Functions
Signal Processing
Audio signals are analyzed using microprocessor-based SAT
and must produce specific frequency, signature, and timing
relationships to cause an alarm. The sophistication of this
processing technique insures proper catch performance
while eliminating false alarms.
Test Features
The push button operated test mode provides a location
verification and operational test when using the optional
DS1110i glassbreak tester. Test mode also includes an
environmental test that alerts the installer to possible false
alarm sources caused by ambient noise. Automatic sound
check feature allows the end user to verify that the detector
is powered and functioning by clapping his hands.
Externally visible alarm LED indicates an alarm or test
condition and can be programmed to latch if desired.

Installation/Configuration Notes
Note Glassbreak detectors are intended only as a
component of a perimeter protection system.
They should always be used in conjunction
with motion sensors.
Mounting
Mount the DS1109i on the ceiling, or on the wall opposite
or, adjacent to the window. Coverage depends on room
acoustics and window size.
